Rudolf Modrzejewski
Ralph Modjeski (born Rudolf Modrzejewski; January 27, 1861 – June 26, 1940) was a Polish-American civil engineer who achieved prominence as "America's greatest bridge builder." Life He was born in Bochnia, called Galicia at the time, on January 27, 1861, to Gustav Sinnmayer Modrzejewski and actress Helena Opid Modrzejewska (best known outside Poland as Helena Modjeska). In 1865, his mother left Sinnmayer, and in 1868, she married "Count" Karol Bożenta Chłapowski. In July 1876, they emigrated to America, where, as a matter of convenience, the boy's mother changed her name to Helena Modjeska and her son's name to Ralph Modjeski. He was a classmate of Ignacy Jan Paderewski in Poland and was a formidable pianist in his own right. The son returned to Europe to study at ''l'Ecole des Ponts et Chaussées'' (the School of Bridges and Roads) in Paris, France. It was in 1883, while studying at Paris, that he obtained American citizenship. However, he always maintained contact with Po ...

Bochnia
Bochnia (german: Salzberg) is a town on the river Raba in southern Poland. The town lies approximately halfway between Tarnów (east) and the regional capital Kraków (west). Bochnia is most noted for its salt mine, the oldest functioning in Europe, built in the 13th century, a World Heritage Site and a Historic Monument of Poland. Since Poland's administrative reorganization in 1999, Bochnia has been the administrative capital of Bochnia County in Lesser Poland Voivodeship. From 1975 to 1998 it was a part of Tarnów Voivodeship. As of December 2021, Bochnia has a population of 29,317 and an area of . History Bochnia is one of the oldest cities of Lesser Poland. The first known source mentioning the city is a letter of 1198, in which Aymar the Monk, Latin Patriarch of Jerusalem, confirmed a donation by the local magnate Mikora Gryfit to the monastery of the Order of the Holy Sepulchre in Miechów. The discovery of major deposits of rock salt at the site of the present min ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Government Bridge
The Government Bridge or Arsenal Bridge spans the Mississippi River, connecting Rock Island, Illinois and Davenport, Iowa. The Iowa Interstate Railroad uses the upper deck of the bridge for its ex-Chicago and Rock Island Railroad route between Council Bluffs, Iowa and Chicago, Illinois. The lower deck carries automobile traffic between the two cities. It is located near Upper Mississippi Mile Marker 483, adjacent to the Mississippi River Lock and Dam No. 15. The current structure (which was completed in 1896) is the fourth at this location. The bridges all were built with a swing section to accommodate traffic navigating the river. The first Rock Island Bridge, which was finished in 1856, was the first railroad bridge across the Mississippi. The bridge was long, and the draw-span was . It was located upstream from the current bridge. It was a threat to the South (which sought to create a southern rail route to the Pacific) and to St. Louis, whose steamboats faced competition f ...

Honoris Causa
An honorary degree is an academic degree for which a university (or other degree-awarding institution) has waived all of the usual requirements. It is also known by the Latin phrases ''honoris causa'' ("for the sake of the honour") or ''ad honorem '' ("to the honour"). The degree is typically a doctorate or, less commonly, a master's degree, and may be awarded to someone who has no prior connection with the academic institution or no previous postsecondary education. An example of identifying a recipient of this award is as follows: Doctorate in Business Administration (''Hon. Causa''). The degree is often conferred as a way of honouring a distinguished visitor's contributions to a specific field or to society in general. It is sometimes recommended that such degrees be listed in one's curriculum vitae (CV) as an award, and not in the education section. With regard to the use of this honorific, the policies of institutions of higher education generally ask that recipients ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

San Francisco–Oakland Bay Bridge
The San Francisco–Oakland Bay Bridge, known locally as the Bay Bridge, is a complex of bridges spanning San Francisco Bay in California. As part of Interstate 80 in California, Interstate 80 and the direct road between San Francisco and Oakland, California, Oakland, it carries about 260,000 vehicles a day on its two decks. It has one of the List of longest suspension bridge spans, longest spans in the United States. The toll bridge was conceived as early as the California Gold Rush days, with "Emperor" Joshua Norton famously advocating for it, but construction did not begin until 1933. Designed by Charles H. Purcell, and built by American Bridge Company, it opened on Thursday, November 12, 1936, six months before the Golden Gate Bridge. It originally carried automobile traffic on its upper deck, with trucks, cars, buses and interurban, commuter trains on the lower, but after the Key System abandoned rail service on April 20, 1958, the lower deck was converted to all-road traffic ...

Golden Gate Bridge
The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the strait connecting San Francisco Bay and the Pacific Ocean. The structure links the U.S. city of San Francisco, California—the northern tip of the San Francisco Peninsula—to Marin County, carrying both U.S. Route 101 and California State Route 1 across the strait. It also carries pedestrian and bicycle traffic, and is designated as part of U.S. Bicycle Route 95. Being declared one of the Wonders of the Modern World by the American Society of Civil Engineers, the bridge is one of the most internationally recognized symbols of San Francisco and California. It was initially designed by engineer Joseph Strauss in 1917. The bridge was named for the Golden Gate strait, the channel that it spans. The Frommer's travel guide describes the Golden Gate Bridge as "possibly the most beautiful, certainly the most photographed, bridge in the world." At the time of its opening in 1937, it was both the longe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Joseph B
Joseph Ber Soloveitchik ( he, יוסף דב הלוי סולובייצ׳יק ''Yosef Dov ha-Levi Soloveychik''; February 27, 1903 – April 9, 1993) was a major American Orthodox rabbi, Talmudist, and modern Jewish philosopher. He was a scion of the Lithuanian Jewish Soloveitchik rabbinic dynasty. As a '' rosh yeshiva'' of Rabbi Isaac Elchanan Theological Seminary at Yeshiva University in New York City, The Rav, as he came to be known, ordained close to 2,000 rabbis over the course of almost half a century. Rabbinic literature sometimes refers to him as הגרי"ד, short for "The great Rabbi Yosef Dov". He served as an advisor, guide, mentor, and role-model for tens of thousands of Jews, both as a Talmudic scholar and as a religious leader. He is regarded as a seminal figure by Modern Orthodox Judaism. Heritage Joseph Ber Soloveitchik was born on February 27, 1903, in Pruzhany, Imperial Russia (later Poland, now Belarus).

Suspension Bridge
A suspension bridge is a type of bridge in which the deck (bridge), deck is hung below suspension wire rope, cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world. Besides the bridge type most commonly called suspension bridges, covered in this article, there are other types of suspension bridges. The type covered here has cables suspended between towers, with vertical ''suspender cables'' that transfer the Structural load#Live load, imposed loads, transient load, live and Structural load#Dead load, dead loads of the deck below, upon which traffic crosses. This arrangement allows the deck to be level or to arc upward for additional clearance. Like other suspension bridge types, this type often is constructed without the use of falsework. The suspension cables must be anchored at each end of the bridge, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cantilever Bridge
A cantilever bridge is a bridge built using structures that project horizontally into space, supported on only one end (called cantilevers). For small footbridges, the cantilevers may be simple beam (structure), beams; however, large cantilever bridges designed to handle road or rail traffic use trusses built from structural steel, or box girders built from prestressed concrete. The steel truss cantilever bridge was a major engineering breakthrough when first put into practice, as it can span distances of over , and can be more easily constructed at difficult crossings by virtue of using little or no falsework. Origins Civil engineer, Engineers in the 19th century understood that a bridge that was continuous across multiple supports would distribute the loads among them. This would result in lower stresses in the girder or truss and meant that longer spans could be built. Several 19th-century engineers patented continuous bridges with hinge points mid-span. The use of a hing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Truss Bridge
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and th ...
